This invention krelates to improvements in shavingbrushe's, and particularly tok Ameans for' securing. the brush l bristles together Y and '.inthesocket of the brush handle. r

` 5 "'Thejobject of the inventionis to provide il simple',` reliable' andi inexpensiveV means for "holding the bristles in such a secure-manner Y. .that the kfastening means will be prooi vagainstjthe bristles or fastening means be,- ,lo

- fior other high heaty treatment.

coming loose when subjected to sterilization 'Inthe accompanying drawingf-y b 7 Figure l is a longitudinal sectional view ,l y'through' a shaving brush showing one form 1'5 i of the invention.

finner ends ot the bristles a arefitted within a v metallicferruler or'thimble b, yand a Aplug c bristles confined by theL thimble. rllhis plug y' Y is provided with anannular groove d. After the bristles, thimble and plug are assembled V25V thefthimble is compressed or crimped to pro.- ducevan annular indentation e on a plane coinciding with the grove (l, whereby the inter? Y vening portions of the bristles are crimped andtighty compressed .or clamped between i interlocked therewith.

i .ing the errule of metal, it may be made'of y"same composition material which will not bev` affected Vby sterilizing temperature, butmay Ibe ,softened by yheatfat Vhighery temperatures 'so that it may-be shaped toy produce the crimp or indentationv e. For securingvthe Lkthus clamped bristle tuft in thehandle f, an anchor" comprising a=pluralityo hook-shaped an# l ch'or pinsv gis' provided- Theser pins are driven` into the tuft before'the thirnble is crimped. The anchor pinsprojectjbeyond the" confined ends'of'thebristles and are di'sposed in suitablyspaced relationship to each other. The handle fr'ispr'ovided with a socket having an outer portion 71, which receivesthe thimble and clamped ends or" the kbristles and aninner lportion fh'which re-v y yFigures 2 andare similarviews showing,

otherforms of the invention. In the construction shown in Figure l, the

ceives the anchor pins Prior to the fitting of the tutt into the socket, the socketportion h is filled with a suitable rapidly setting cement 'zo'. which when set will hold the clamped posed portions'of the bristles and protected by the Wall of the handle,the brush may be subjected: to high `sterilizing temperatures without in any manner affecting the integrity of the l connection of the bristles vwith the handle.; 'Y 1 l ,A i y f f In the 'construction shown in Figure 2 the anchor pins1 gare ldispensedwith and the vplug-ais lprovided with an integral anchoring stem c whichfextends intoY the inner portion h2 ofthe'handle socket', which is of outwardly tapering form.. The stemde" is shaped like a screw, or: provided 'with grooves 'or threads and a terminal head1 for a secure interlocking connection with the cement or setting yagent i. Thetapering form of the socket portionl here prevents any possibility of outward displacement ofthe cement body. v l` In thevconstruction shown in F igure the yplugc is providedf -with 1a projecting anchor stemwhich is split to form a plurality of 'curved retaining' prongs .02, which are embedded in the 'cement filling i', making a secure anchor.l Inthisv form of the invention the inner socket portion'h2 is also tapered as in the construction shownin Figure 2.

The inode of "manufacture, and construction described providesv for the firm clamping ofthegbristles and assemblage of the parts in an easy, convenient, time-Savin g and inexpensive-manner, and-in`the reliable holding of With the bristles in the socket of the handle. this construction the' brush may be sterilized Vrepeatedly without in any manner yaii'ecting the integrity ofthe'connection between -the bristlesV and the'handle. f
